APPARATUS FORTIREATING- TEXTILE FIBERS WITHLIQUIDS ANID GASES.

To all whom it may concern Be it known that we, JOHN BRANDwooD, THOMAS BnANDwooD, and EDWARD BRAND- woon, all subjects of the King of Great Britain and Ireland, and all residents of Bury, in the county of Lancaster, England, have invented certain new and useful Improvements in Apparatus for Treating Textile Fibers with Liquids and Gases, of which the following is a speciiication'.

lThis invention relates to apparatus in which cops or the like may be first treated with liquid asin dyeing or bleaching andv may then be treated without removal with any suitable gases or vapors.

Apparatus constructed according to this invention comprises a keir or other like closable vessel divided into upper and lower compartments by a partition. The two compartments thus formed are of unequal capacities and are ofsuch capacities and the quantity of liquid employed is such tha.; while the upper chamber during the liquid treatment process will be full of or contain liquid at any desired pressure-whenv the apparatus is working to force the liquid through the cops or the like 4which are placed upon the upper surface of the partition, 'such liquid can all be contained in the lower compartment and its connected pump or the like with space to spare when the liquid treatment has ceased, and this without the provision of any storage tanks extra to the apparatus'. When t-he liquidtreatment has ceased and the liquid is contained in the lower compartment the cops can then be treated by air or other gases or the like While still in the positions which they occupied for liquid treatment. By a reference to copsis to be understood also ready referred to.. Fig. 3 is a vertical sec-A tional view of a detail.

Referring to the drawings, A is an approximately vertical` cylindrical keir closed Specification of Letters Patent.

at its bottom and furnished with a removable cover B at its upper end.

C a horizontal partition dividing the keir into upper and lower compartments D, D1. The partition C is formed with a` number of holes E and in each hole may closely `tit a plate F carrying perforated spindles bearing cops G, the open ends of the perforated spindles coming to the under faces of the plates F.' lVhen each hole E has its plate F in place then communication between the upper and ower compartments D D1 inside the keir can only be through the perforated spindles and the librous matter borne by them.4 The use of such spindles is of course well known in cop dyeing.

H is a centrifugal pump; J a pipe, and J1 Jl branches thereof by means of which dye or other liquor is forced from the pump into the upper Compartment D; and K is a pipe from the bottom of the lower compartment D1 to return liquid Jfrom such compartment to the pump.

L is an air inlet pipe opening into, the upper compartment and M is an air outlet or suction pipe leading from the upper part of the lower conipartment. Instead of air,

other gases or vapors may be used, but they ment, but not suilicient to fill the lower andlarger compartment by several inches. The pressure in the upper compartment continuall7 forces liquid through the fibers of the cops and the perforated spindles, which liquid falls into the lower compartment and i returns to the pump by which it is again sent to theA upper compartment. During this liquid treatment the air pipe M may be open but the pipe L will -be closed. 7When the liquid treatment is finished and the pump stops, any liquid which is left in the upper compartment runs down into the lower compartment. It may do this through the branches J1 which are set. with the lower portions of their channels level with the upper face or even slightly lower than the upper 'face of the partition C, and throuvh the pipeJ, the pump H, and pipe K. r drainage from the upper compartment to the lower may be by means of a plug outlet or equivalent formed in the partition. `When the liquor has run out of the upper compartment and is say standing at l cover of the keir; it may be by forced passage of air which is admitted to the upper compartment D under pressure through the pipe L when the cover of the keir is closed. With air under pressure the pipe M would be the escape pipe. Theair compressing or suction appliances are not shown in the drawings.- They may be of any usual construction.

It is for treatment with air under externally applied pressure that the apparatus is particularly suitable. The air should be supplied under such a heavy pressure and in such volume as to insure that air passes through the substance ofthe various yarns or the like and not merely through the intersticcs between them.

Fig. 3 shows how the plates F may be simply dropped in place in the holes E in the partition C and will seal themselves against pressure from above. The edge of each plate has a downwardly` depending flange f which comes upon a rubber or like packing ring e placed in a seat surrounding the hole E. The weight of the plate and the pressure of liquid or air from above makes a tight joint. The plates are easily lifted out when the cover of the keir is lifted.

What we claim is V- l l. Apparatus for first treating vcops with liquid and then treatilur them with air without removing them, such apparatus comprising a keir, a transverse partition `therein for bearing the cops and dividing the keir into upper and lower compartments of which the lower is the larger, a liquid circulating pump and its pipes, air andplquid inlets to the upper compartment, and air and liquid outlets in the ower compartment, substantially as set forth.

3. Apparatus for first treating cops with liquid and then treating them with air without removing them, such apparatus comprising a keir, a'transverse partition therein dividing the keir into upper and lower compartments of which the lower is the larger, seated holes formed in such partition, cop l carrying plates to seat themselves around s'uch holes, a liquid circulating pump and its pipes, air and liquid inlets to the upper ccmpartment, and air and liquid outlets in the lower compartment, substantially as set forth. n
